The main board sub board and charger port board can all be disconnected and removed. The screen can be replaced by heating the front of the phone prying the screen off the frame and running the cable through the mid frame. The battery can be removed by applying heat and using a plastic pry tool. The device also has several rubber gaskets and a copper tape to help transfer heat. Overall the Samsung Galaxy M51 is a fairly repairable device and deserves a score of 7.0/10.
